This is a video of some common terns that I digiscoped at South Beach in Massachusetts recently and there was some beach bird family drama.
It was too funny because the terns had young that were just out of the nest and old enough to fly--teenagers. They were in that stage of teaching the young to fish for themselves, rather than constantly begging their parents. One young bird in particular was not getting it. The adult bird at first makes a big show of preening its feathers and ignoring the demanding youngster.

The young bird even tries picking up little sticks on the beach as if showing the adult, "Hey, you used to bring me fish this size to eat, I want that now, see?"

The adult just kind of tosses it away, "You don't want that kid."

Eventually the other adult in the pair lands and give the kid a good, swift kick in the rear to get it to fly--it's hilarious.
